Channel security

When you are using channels, the security features available depend on which communications protocol you are going to use. If you use TCP, there are no security features provided with the communications protocol, although we can use SSL. If you are using APPC, we can flow user ID information from the sending MCA through the network to the destination MCA for verification.

For both protocols, we can specify which user IDs you want to check for security purposes, and how many. Again, the choices available to you depend on which protocol you are using, what you specify when you define the channel, and the RESLEVEL settings for the channel initiator.

We can also write your own security exit programs to be called by the MCA.
